Title: A communications system and method for interconnected networks having a linear topology, especially railways
Inventor: DARBY ALBERT DONALD JR
IPC: H04B7/15
Filed: 1998-03-17
Granted: 2007-10-02
Abstract: A system and method for communicating over networks, particularly generally- linear networks such as a network of railcars in a railway train. The disclosed system and method include the relaying of packe ts which may contain plural messages down a line of nodes. Acknowledgement of the packets is obtained implicitly by listening to a subsequent relay of the packet and retransmission of the packet is effected on a diverse antenna in the event of non-acknowledgement. Message bandwidth is shared among the nodes of the system by a message priority system and by the reservation of portions of a packet for certain types of messages. Message bandwidth is also shared by the use of groups of nodes as relay participants and by periodically changin g the group which is performing the relay operations.

Abstract: Tasteless super-purified smoke is manufactured to treat seafood and meat to preserve the freshness, color, texture, and natural flavor, particularly after the food is frozen and thawed. The smoke is generated by burning an organic smoking material at preferably 500 to 800 degrees F. (260 to 427 degrees C.) in a smoke generator (1). It is then passed through a precipitation filtering tower (2) comprised of filters of ice, cloth, and activated carbon to remove taste imparting, and carcinogenic, particulates and vapors. The super-purified smoke is then stored and aged in a temporary pressure pot (3) or in canisters for treatment at the same time or at another place and time. The super-purified smoke is used to treat seafood or meat in plastic bags at temperatures between its variable freezing point 46 degrees F. (7.8 degrees C.) for twelve to forty-eight hours, or until the desired effect is achieved. The product is then frozen, stored for up to one year, and quick or slow thawed with little degradation of the treated seafood or meat.
